Because raw material availability decreases each year, these cufflinks are lasting heirloom pieces.

Our Derbyshire Blue John jewellery features this semi-precious mineral which was formed several million years ago.

Blue John is a form of fluorite with bands of a purple-blue or yellowish colour. The name Blue John may come from a corrupted of the French “Bleu jaune” - “blue yellow”.

It is only found in the UK in one location – the Blue John Cavern and Treak Cliff Cavern in Castleton, Derbyshire.

Blue John is becoming rarer and mining is now extremely limited each year, with only a small amount being made into jewellery.
